a 3D file converted to 2D and cut out

[woodman12]

This is a perpetual calendar 3d file from Hariprasad in India,he designed it from an old childhood toy his father gave him.
I took the 3d file and worked at it to get 2D parts from it then cut it out.I see now how it works and i will need to sandwhich it between two
pieces of plexiglas and leave some open slots to adjust the rings for date and day changes
